* stand: create common set_currdevWarner Losh2023-01-241-0/+17
| | | | | | | | | | | | | | Pull together the nearly identical copies of set_currdev in i386, userboot and efi. Other boot loaders have variances that might be fine to use the common routine, or not. Since they are harder to test for me, and ofw and uboot do handle these setting differently, leave them be for now.

* stand: Move dev_cleanup into libsaWarner Losh2023-01-241-11/+0
| | | | | | | | | | | | | | | | Since dev_cleanup() walks through all the devsw devices with dv_cleanup rotuines, move it into libsa rather than having it in 'common'. Logically, it operates only on things that are in libsa, and would never be different for different loaders: either people would call it as is, or they'd do the loop themselves with 'special' things inline between calls to cleanup (not that I think that will ever be needed though).

* stand: Create common gen_setcurrdev and replace codeWarner Losh2023-01-241-0/+16
| | | | | | | | | | | | Replace 4 identical copies of *_setcurrdev with gen_setcurrdev to avoid having to create a 5th copy. uboot_setcurrdev is actually different and needs to remain separate (even though it's quite similar).

* veloader use vectx API for kernel and modulesSimon J. Gerraty2020-03-081-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vectx API, computes the hash for verifying a file as it is read. This avoids the overhead of reading files twice - once to verify, then again to load. For doing an install via loader, avoiding the need to rewind large files is critical. This API is only used for modules, kernel and mdimage as these are the biggest files read by the loader. The reduction in boot time depends on how expensive the I/O is on any given platform. On a fast VM we see 6% improvement. For install via loader the first file to be verified is likely to be the kernel, so some of the prep work (finding manifest etc) done by verify_file() needs to be factored so it can be reused for vectx_open(). For missing or unrecognized fingerprint entries, we fail in vectx_open() unless verifying is disabled. Otherwise fingerprint check happens in vectx_close() and since this API is only used for files which must be verified (VE_MUST) we panic if we get an incorrect hash.
